This book has definitely helped me to understand several aspects of Yoga. The main purpose of reading this book was to go beyond the idea which already persisted within over the period of time. Being Yoga Practitioner for several years and India Book of Records holder for holding Janusirsana (Yoga Pose) pose for longest duration, I thought I know everything about Yoga. This book was an eye opener. True form manisfests itself if one desires to and I am glad to know that I know nothing about Yoga and will soak more deeply to know and experience it in its purest form. I recommend this book to everyone out there who believes Yoga is only about physical exercises and also to ones who do not truly knows what Yoga is all about.
